v0.1.45

Added

• okf agent REPL — interactive multi-turn chat over a bundle with persistent sessions (~/.okf/sessions/), slash commands (/lookup, /source, /calls, /called-by, /related, /save, /export, /history, /sessions, /resume), and session export to JSON/Markdown.
• Tree-sitter WASM parse tree in viz — the code panel now has a "Parse Tree" tab that renders the full tree-sitter AST with collapsible scopes, syntax-colored tokens, and position ranges. Supports 10 languages (Python, JS, TS, Ruby, Rust, Go, Java, C++, C, PHP); remaining languages fall back gracefully.
• Glass UI redesign — frosted glass cards with backdrop-filter:blur(24px), translucent backgrounds, soft-light bg image overlay, breathing gradient animation. Sidebar, detail panel, stat cards, and chips all use the new glass aesthetic.
• Design tokens — docs/design-tokens.md documents the full color palette, gradients, shadows, spacing, and type colors.
• Theme-specific backgrounds — bg-dark.png and bg-light.png for dark/light mode.
• okf migrate command — converts v0.1 bundles to v0.2 format (okf migrate v0.1-to-v0.2 <bundle_dir>).

Changed

• Viz sidebar and detail panel now live inside frosted glass cards with rounded corners (border-radius:var(--r-xl)).
• Breadcrumb styling: transparent background, translucent borders, sticky position.
• Detail header: spans full card width, glass blur background, no more solid black box.
